Synopsis#include <flint/arb.h>
void arb_sinc(arb_t z, const arb_t x, slong prec)source
void arb_sinc_pi(arb_t z, const arb_t x, slong prec)source

Set z to \operatorname{sinc} x = \sin(x)/x, respectively \operatorname{sinc}(\pi x) = \sin(\pi x)/(\pi x), with the value 1 at x = 0 and accurate enclosures for balls containing 0.
